Our application has a WEB GUI that has an interface to accept the local file location and name. We have written a C# controller that is invoked while clicking submit button. The controller receives the file as HttpPostedFileBase. From the controller, we are trying to invoke the REST API in C# that is expecting the File object as a request however we are unable to do so. The request is expecting the file and the request parameter is of form-data type. Any help to write a C# REST API client to invoke this REST service by passing the file.

below is my model code : PoSPRegistration model

in the above code image is received in HttpPostedFileBase object.

below is controller code : controller post method

can't add image object in request.addfile method because it includes name and filepath

CodePudding user response：

The RestRequest class in RestSharp has an overload of the AddFile method that takes a callback that is called to write data to a Stream object:

AddFile(string name, 
        Action<Stream> writer, 
        string fileName, 
        long contentLength, 
        string contentType = null)

You can use it like that to post data from a HttpPostedFileBase:

request.AddFile("pan", 
                stream => objmodel.doc_pan.InputStream.CopyTo(stream), 
                objmodel.doc_pan.FileName, 
                objmodel.doc_pan.ContentLength, 
                objmodel.doc_pan.ContentType);
